HAY LOADER AND STAOKER.

SPECIFIGA'IION forming part of Letters Patent No. 777,55, dated December13, 1904.

Application filed April 16, 1904.

1'0 (all. whom it Duty concern.-

Be it known that we, ALLIsoN F. SNYDER and WALTER A. SNYDER, citizens ofthe United States, residing at Alliance, in the county of Boxbutte andState of Nebraska, have invented a new and useful Improvement in HayLoaders and Stacker-s; and we do hereby declare the following to be afull, clear, and exactdescription of the same.

This invention relates to that class offal-1ningimplements which areused for loading and stacking hay; and its object is to provide meanswhereby the power of a team may be used to raise hay up from the groundand dump it onto a haystack or onto a wagon.

To this end our invention consists in the construction and combinationof parts forming a hay stacker and loader hereinafter more fullydescribed, and particularly defined in the claims, reference being hadto the accompanying drawings, in which Figure I is a perspective view ofa hay loader and stacker according to ourinvention with the fork restingon the ground. Fig. 11 represents the same in longitudinal verticalsection, taken at the near side of the midway pieces and showing thefork elevated to the position of dumping a load.

Numeral 3 represents the side bars of the frame, which rest on theground and are slanted up at their forward end to be dragged over thefield like a sled.

4:, 5, 6, and 7 are cross-bars of the frame, rigidly secured to the sidebars 3.

A rack comprising two posts 8, which are secured rigidly to the sidebars 3 and the crossslats 9, secured to the posts, serves as a fence tokeep loose hay from tumbling onto the bed of the frame.

The fork comprises a series of lingers 10, cross-bars 11 12, side bars13 14, and the head 16. The fingers 10 are rigidly fixed upon thecross-pieces 11 12, which are fixed upon two side bars 13 and 14. Theside bars are mounted to rotate upon a journal 15, located near the rearend of the frame, in being raised to the vertical position shown in Fig.II. The

head 16 is provided with fingers 20 and is hinged to the cross-bar 12 insome substantial manner, such as by the eyebolts 17, and it is SerialNo. 203,502. (No monleh provided with springs 18, which may be connectedwith it, each by a short lever 19. The other ends of the springs areconnected, respectively, with the side bars 13 141, the action of thesprings being to throw the head into the position shown in dotted linesin Fig. ll.

21 represents the derrick, conmrising two bracing side posts 22 and thecross-bars 23, 24L, and 25, rigidly secured thereto. This derrick ismounted to swing backward and forward upon a journal 26, that is fixedin the framebars 3 forward of the journal 15 of the hayfork.

27 is the boom, mounted between the upper ends of the side posts 22 ofthe derrick to swing upon a short journal 28. The boom is provided withpulleys 29 and 30, over which the draft-rope 31 travels. At oneend thisrope is attached to the forward end of the boom 27. Thence it passesdown around a pulley 46, which is attached to a bail-chain 32, thenceback over the pulley 29. The bail-chain 32 is connected directly withthe side bars 13 14: of the fork. The rope 31 is provided with a hook233, to which a horse or other motive power may be hitched to draw itaway from pulley 34:. This pulley 34 is mounted to revolve in a block35, that is freely hung at 36 to the cross-bar 6 of the frame, so thatthe pulley and block may adapt themselves to the direction of pull onthe rope.

37 and 38 are pulleys mounted to revolve upon a journal 39, and 10represents collars to keep the pulleys in place on the rod.

41 is a pulley hung to the under side of the boom 27, nearly midwaythereof.

42 represents shields over the rope 31 to prevent it from running offthe adjacent pulleys.

17 is a stop-lug clamped upon the rope to strike against the rear shield12, so that the last action of the rope may be expended upon the boom todraw it close down, as shown in Fig. 11, to swing the top of the boomand fork backward in discharging the fork.

13 represents springs, one of which connects each fork-beam 13 and 1 1with the adjacent side beam 3 of the frame.

4 1 represents two ropes indepei'idently connecting the forward end ofthe boom 27 with the side bars 13 14 of the fork. Their action is tobring the boom nearly into line with their points of attachment, so thatthe boom may lift to the greatest advantage at the instant of startingto raise the loaded fork.

The operation is as follows: The machine is to be located with its rack8 9 against the side of the stack or wagon to be loaded. Then the forkin the position shown in Fig. Iis to be filled with hay. Now if the teambe set to pulling at the hook 33 the rope traveling around pulleys 34,37, 41, 38, 30, and 29 draws, by means of the bail-chain 32, directlyupon the side bars 13 14 of the fork to lift it. As soon as the ropebecomes taut it will begin to pull the rear end of the boom downward,thus starting the forward end of the boom to lifting the fork and itsload by means of the bailchain 32, aided at this time of greatest strainby the independent ropes 44. As the rear end of the boom 27 approachesnear to the pulley 38 its lifting advantage decreases until the line ofleast resistance to the pulling of the rope is between the forward endof the boom and the fork, so that as the movement of the rope continuesit travels around the pulley 46 and the fork is pulled toward the boomand the side ropes 44 hang slack. The lug 47 reaches the rear shield 42before the shortest distance between the chain 32 and the pulley 29 isgained, and from that time the lower end of the boom is being drawnforward toward the pulley 38 and the top end of the boom is swungrearward, carrying the fork over center. When the fork approaches thevertical position, (shown in Fig. 11,) the Weight of the load restslargely upon the fork-head 16 20; but the ease with which the fork isswung over the vertical center enables the operator to give the load athrow, if he so desires, at the last moment, and when the load leavesthe fork the last portion of it is given a flip by the springs 18,throwing the fingers 2O upward, thus throwing the whole load of hay uponthe stack. In passing over center the fork-bars l3 l4 draw out thesprings 43, and as soon as the load is thrown off from the fork thesesprings pull the fork forward until its own weight will return it asrapidly as the slackening of the draft-rope permits until it reaches toits normal position of rest, as in Fig. I.

Some of the advantages of this hay loader and stacker are, first, itsability to handle heavy loads with ease; second, its ability to throwthe load all upon the stack, and, third, the ease with which its forkreturns to 'its normal position after each lift.

It is evident that all the pulleys are mere well-known devices forchanging the direction of the rope and for lessening friction. Thereforethey are mentioned in the claims only for the purpose of elucidating thechain of thought, and any equivalent for them may be substituted. It isalso evident that the pulleys 41 and 46 might be dispensed with; butthat would lessen the leverage and demand more power to work themachine.

Having thus fully described our invention, what we believe to be new,and desire to secure by Letters Patent, is the following:

1. In hay loaders and stackers, a frame to rest upon the ground; ahay-fork having two side bars journaled to the frame near its rear end;a derrick journaled to the frame forward of the hay-fork journal; a boomjournaled to the upper end of the derrick; a pulley mounted in the boomat each end thereof and another pulley hung midway of the boom; twopulleys 37, 38, journaled in the frame, another pulley 34, freely hungto the frame; a draft-rope passing over the said pulleys as described,and a bail connecting this rope with the two side bars of the hay-fork.

2. In hay loaders and stackers, a frame; a hay-fork journaled thereto; aderrick journaledin the frame; a boom journaled in the derrick; pulleyssecured to the derrick and the frame; a draft-rope running over thepulleys and connected with the hay-fork, and connections between thehay-fork and the derrick independent of the draft-rope, whereby thefirstlift upon the fork is made by the action of the draft-rope throughthe boom, and the lift is finished by direct pulling of the ropesubstantially as described.

3. In hay loaders and stackers, a frame; a hay-fork journaled to swingup and down thereon; a head to the fork, provided with teeth and hingedto swing to and fro on the fork, and springs connecting the head withthe fork.

4. In hay loaders and stackers, a frame; a hay-fork journaled thereon,to swing upward and rearward; a derrick attached to the frame; a boomjournaled on the derrick; rope-shields upon the boom; a rope connectedwith the fork and mounted to travel longitudinally over the boom, and alug secured to the rope to engage the said shields substantially asshown and described.

In testimony whereof we affix our signatures in presence of'twowitnesses.
